Eclipse debug not finding the code block

I am new to eclipse(europa - 3.3.0) debugging feature. I added breakpoints at various places in my code. But while debugging(running the application with Jboss - port:8787), eclipse finds the java file where the breakpoint is present, but it is not going to the exact line/block of code. In the debug dialog i can see "line: not available". I think i have attached the source correctly since it finds the file. I have attached the screenshot of the eclipse debug dialog.

* Very comfortable and sophisticated support for Xdoclet.
* Debugging and monitoring of JBoss servers and controlling of their life cycles. * An easy way to configure the packaging layout of archives (packed or exploded).
* A simple way to deploy the packaged and/or exploded archive to a JBoss server
